Manager Magazin questions the SAP platform, stating that SAP's many acquisitions "were put under a single [S/4HANA] brand but not on a single technology platform, much to the dismay of SAP customers." (Manager Magazin, "Why SAP is losing the connection," 18 Feb 2021). Even the head of SAP's German user group DSAG – Jens Hungershausen – is skeptical, stating in the same Wirtschaftswoche article that "the migration to S/4HANA is such a mammoth undertaking, customers may as well consider alternatives."
More recently, Morgan Stanley questions SAP's strategy, stating, "The key investor debate on SAP continues to be around its cloud transition-and therefore around Cloud subscription growth." (Morgan Stanley, "Can Cloud outperform this year?" 1 June 2021).

SAP business processes that cut across 1990s departmental silos
The integration that came along with SAP ECC or Business Suite (and is no longer there in S/4HANA)
The ability to customize SAP
The ability to work with SAP in real time
The large number of companies that were using SAP, possibly including your competitors and business partners
